Hey guys, I'm looking to replace my cruise control vacuum actuator, the rubber diaphragm on mine is cracked and the CC doens't work. My car is an 83 Crossfire. My question is would the vacuum actuator from an 84 carbed car work as a replacement for mine? A local guy has one on craigslist for cheap.

Any help is appreciated
